C3 Environment variables

News  C3 Tools Recommended Links Unix Configuration Management Tools Options Examples C3 Environment variables
c3.conf cpush cexec cget crm    
rdist rsync   Tips History Humor Etc

C3_RSH

 
By default, the C3 tools will use ssh to issue the remote commands. If you would like to have them use rsh instead, you must set the C3_RSH environment variable to rsh.
 
For example, if you are using the bash shell you would do the following:
 

export C3_RSH=rsh
 

any program that behaves like rsh or ssh is acceptable

 

C3_PATH

 
The default install path for C3 is /opt/c3-4. If you install C3 in an alternate location this variable must point to that installation. For remote clusters C3 must be installed in the same directory on each cluster.
 
For example, if you installed C3 in your home directory you might use the following:
 

export C3_PATH=/home/sgrundy/c3-4
 

 

 

C3_CONF

 
C3's default configuration file is /etc/c3.conf. If you wish an alternate default configuration file set this to point to the file
 
For example, if you keep a special c3.conf file in your home directory you may use:
 

export C3_CONF=/home/sgrundy/.c3conf
 

 

 

C3_USER

 
By default, the C3 tools will use your local username to access a remote cluster. If you wish to use a different default then set this variable to it
 
For example, this will change the example user from sgrundy to mmanhunter:
 

export C3_USER=mmanhunter
